They are NOT from the same factory. The original plant (ironically called "Svetlana") that made SED =C= tubes is dead. No more tubes from them.
Svetlana tubes are made at the New Sensor factory (along with EH, Tung Sol, Mullard, Gold Lion and Sovtek tubes).
In comparison with other tubes they are somewhat neutral. We usually use them in amps/situations where we don't want the original tone colored much.
I was looking for something that can add a little "Marshall" flavour to my sound but I haven't found anything (and nobody answered my post in Diezel forums) so I decided I should buy these Svetlanas. I dunno, there aren't many "good" tubes to choose from, JJs - not very durable, EHs - I don't like them, SED - no more available, etc. and not every tube is available in my country, so I had to choose between EH, JJ, Tung Sol, Shuguang and Svetlana.
But! If anyone knows tubes with "Marshall flavour" and not much low end write me a PM, because I haven't paid for it yet so I can cancel my order.
